The US currently spends around $5 billion per year in energy
research and development, according to
a 2015 report by the American Energy Innovation Council, a
committee of six executives including Gates.

The details of the new investment and partnership are still
unclear, but it will mark the largest financial effort yet in the
fight against climate change.

"Digital technology has revolutionized the way people
live," Gates wrote.
"We can create a zero-carbon future too, if we commit to
it."
